IMPROVEMENT IN CULTIVATORS. i

Specification forming part of Letters Patent No. 50,093, dated September 26, 1865.

.To all whom it may concern Be it known thatI, WILLIAM J. BURTON,

of Turtle, in the countyof Rock, in the State of' Wisconsin, have invented a new and usef'ul 'Improvement in Uultivators, which invention relates to a new and improved machine'for cultivating corn; and it consists in a peculiar construction and arrangement of parts,l whereby it is believed that several advantages are obl Figure 1 is an isometrica] view. 4a a, E, D, b

11, B B, B B, C C, and F F exhibit a standard projection or workin g model. a a is the head or beam, to which thestandards'b b are attached as shown, to the lower ends of which the iron braces or shan ks B B arefastened by two three-` eighths bolts to each, to the lower extremity of which the cultivator teeth or hoes B B are fixed by bolts, as represented at B, Figs. 3 and 4. D represents the tongue, as shown in Fig.2. E E are the hounds or braces supporting the tongue, as clearly seen in Fig. 2. F F are the handles; and C C, bows having steel shoes c, the upper 'ends passing through -thebeam a a at af, Fig. 4, through a metal box or thimble, permitting the bows tewerk loosely on the polished surfaces of theinterior of said boxes or thimbles, the polished steel vshoes 'aforesaid also working easily on the surface of the ground when in use as a cultivator. The pins or keys through said bows above and below the beam a a at a, Fig. 4, can. be inserted through the holes in said bows higher up: or lower down, thereby raising or lowering the beam a a, -rendering the cultivator adjustable toan y desired depth. '1

Fig. 2 represents a top-section view, which has been adverted to..-

Fig. 3 is a cross-section-view taken in' the line of F F and D as near as may be. Fig- 4 is a similar view taken near the ends of the beam a a. A

Similarletters of reference indicate like parts in all the figures.

Having thus far described the construction and arrangement together of the several parts of the machine in connection with the accomwill )be clearly comprehended from the follow-` panying drawings, the operation of the machine ing explanations: The beam a a is constructed,- ot` pine or other suitable wood, four inches square and twelve feet long, having a halfine band on each end; the tongue, ten feet ten incheslon g and three and one-halfinches square at the heel; the handles, three feet four inches long, spread two feet three inches, one foot ten inches from after partof beam; the aflerrouud, six inches from after part of beam; the bows each two feet ten inches long, one and one-halt' inch thick, with the said pins or keys for raising or lowering the beam for adjusting the cul-A tivator to any desired depth.; sixteen teeth or hoes, so spread and arranged that three rows ot' corn may he cultivated at once, to wit: The letf ters PPP on the beam a a, Fig. 1, indicate three The standards b b are separate rows of corn. two feet four inches long from beam au to end of teeth or hoes B B, including the said shanks or braces, each ten inches long. Said teeth or hoes'arethree landA-onefha'lt by fou'riuches, ot'

steel, and bolted to the shanks or braces, as aforesaid. Said standards b b are each bolted to the beamu a by two three-eighths bolts; all the parts being suitably secured by appropriate ,boltsfor screws. l

This cultivator can be very cheaply constructed, is simple, and easy to operate, accomplishing a large amount of work at small expense ot' time and power. A stout boy often years ean'operate it with ease.V 'The bows, which are used instead of wheels, possess a remarkablefacility for turning the machine and adjustingity to the inequalities and irregularities of crooked rows, the necessary lateral motion being-conveniently communicated at the handles bythe operator, thus being enabled to cultivate, even, crooked rows by this machine without injuring the growingr plants.

Having thusdescrihed the construction and v operation of my said improved machine, so that Y one skilled in the art could make and use the same, what Iclaim, and desire to secure by Letters Patent, Vis Y The bows C C, (this l claim broadly,) the whole arranged as 'and 'for the purpose described and set forth.

In ytestimonywhereof I` have hereunto set my hand and affixed my seal this 13th day of June, A. D. 1865.
